Police say a 3-month-old boy has died after being left in a car alone outside an international market in Greensboro.

Authorities said someone called 911 around 1 p.m. Thursday and said the child strapped inside the car was not moving.

Investigators say people nearby got the baby out of the car and started doing CPR until paramedics arrived, but the boy was pronounced dead at the hospital.

Police say they haven't determined how long the baby was inside the car at the Fanta City International Market. They say the investigation into the incident has just started and no charges have been filed.

The National Weather Service says the temperature in Greensboro was 83 degrees when the baby was found.
